### Question: What are the symptoms of Bornholm disease?
### Response: Symptoms may include fever and headache, but the distinguishing characteristic of this disease is attacks of severe pain in the lower chest, often on one side.  The slightest movement of the rib cage causes a sharp increase of pain, which makes it very difficult to breathe, and an attack is therefore quite a frightening experience, although it generally passes off before any actual harm occurs. The attacks are unpredictable and strike "out of the blue" with a feeling like an iron grip around the rib cage. The colloquial names for the disease, such as'The Devil's grip' reflect this symptom.
Once inside the body, the coxsackie viruses multiply in the throat and intestines then spread into the bloodstream. At this point, the body's immune defenses often can limit the infection and prevent the person from developing symptoms. If the immune defenses are less successful, the person develops a fever or other symptoms, such as headache, nausea and vomiting, and sore throat. Only a few infected people develop the classic muscle pain in the chest and upper abdomen that gives the disease its name. In these people, the coxsackie virus infection has settled in the muscles of the chest and upper abdomen, causing inflammation there. The chest pain usually feels worse with deep breathing, called pleuritic pain. It can be a severe, stabbing pain or it can be a milder cramping in the side. Usually, only one side of the chest or abdomen is affected, although occasionally the pain can include muscles of the neck or arms. The pain usually comes in waves that last 15 to 30 minutes, although some people report having pain episodes that last for several hours. The pain can be so severe that you have trouble breathing, sweat a lot and become anxious.
